Having trouble with ure.match()
Maybe I wrote the regex wrong, but according to regex101.com regex below should return four matches. ure.match("[abcd][01][01]","d00ba11c01d10") When I use ure on "MicroPython v1.14 on 2021-04-11; Raspberry Pi Pico with RP2040" that expression only returns one match (the first one). How do I get to ...

Re: Windows fail to recognize Pi Pico when running this code
Latest MicroPython release "rp2-pico-20210411-unstable-v1.14-152-g6f06dcaee.uf2 (latest)" still has trouble finding the Pi Pico with that main.py.

Re: Windows fail to recognize Pi Pico when running this code
Sorry, I should have thought of including that.
I'm running the latest stable release: "Micropython v1.14 on 2021-02-02; Raspberry Pi Pico with RP2400."
I have not tried the newer unstable versions. I presume replacing the uf2 would clobber all my py code, right?

Re: Is Micropython inherently multithreaded?
Optimisation is an involved process. A first step is to read this doc and this one to learn about MicroPython specific optimisations. There are a lot of ways to improve performance. Peter, I've just scanned those two resources. They're excellent! I will digest them in detail, apply, and time their ...

Re: Is Micropython inherently multithreaded?
Thank you for the replies everyone! If you're interested, here is the dual core version: https://github.com/hwiguna/HariFun_202_MandelbrotPico/blob/main/PicoMandelbrotDualCore.py It works, but it is only marginally faster than the single core version: https://github.com/hwiguna/HariFun_202_Mandelbro...

Is Micropython inherently multithreaded?
After much hair pulling, I was able to get my Mandelbrot calculation run on two threads (core0 as usual, plus core1 via _thread.start_new_thread(). However, it does not run to be twice as fast or anywhere near that. Is MicroPython inherently already multithreaded and I'm just inefficiently trying to...
